Description David Zeuthen 2010-03-01 21:27:28 UTC 
dbus-glib-0.84-2.fc13.x86_64

Recent dbus-glib versions seems to mangle the error name by capitalizing the first letter. I've seen this in many dbus-glib apps - here's an example from udisks

 # dbus-send --print-reply --system --dest=org.freedesktop.UDisks /org/freedesktop/UDisks org.freedesktop.UDisks.LinuxLvm2LVStart string:foo string:bar array:string:
 Error Org.freedesktop.UDisks.Error.Failed: Cannot find Logical Volume with Group UUID `foo' and UUID `bar'

This error doesn't seem to happen with non-dbus-glib bindings, for example, here's polkit (using eggdbus)

 # dbus-send --print-reply --system --dest=org.freedesktop.PolicyKit1 /org/freedesktop/PolicyKit1/Authority org.freedesktop.PolicyKit1.Authority.CancelCheckAuthorization string:foo

 Error org.freedesktop.PolicyKit1.Error.Failed: No such cancellation_id foo for name :1.1038
Comment 1 David Zeuthen 2010-03-01 21:28:45 UTC 
Should fix this for F13 - many apps rely on checking the error name to take appropriate action.
Comment 2 David Zeuthen 2010-03-01 21:35:22 UTC 
Filed the upstream bug here: https://bugs.freedesktop.org/show_bug.cgi?id=26824
Comment 3 Matthias Clasen 2010-03-02 03:45:09 UTC 
This is caused by uscore_to_wincaps being used on error names at
dbus-gobject.c:1083
Comment 4 Colin Walters 2010-03-02 22:20:13 UTC 
Should be fixed by dbus-glib-0.84-3 for f13
